Legal Question in Federal Tort Claims in Texas

Re: What does this mean? Help please Studying Tort Law

"unreasonably dangerous" means more dangerous than a reasonable person would expect. It doesn't mean not dangerous at all. A knife is dangerous. A knife that breaks and flies apart in normal use is unreasonably dangerous. A gun is dangerous; a gun with a super-hair trigger that fires when dropped is unreasonably dangerous. A car is dangerous; a car that bursts into flames in a low-speed crash because the gas tank is wrongly positioned is unreasonably dangerous.
